If we want to customize a nodeId style then we should return the data of the nodeId instead of the generic StyleCollection style.

ConnectionIdUtils:
- Fixed "intNodeId" typo to "inNodeId" in toJson()
- Added backward compatibility in fromJson()

Processing status icons:
- Initialize icons in NodeStyle constructor after Q_INIT_RESOURCE
  (fixes icons not loading due to static initialization order)
- Fixed resource path format from "://" to ":/"
- Skip drawing when status is NoStatus
- Use const reference for ProcessingIconStyle to avoid copy
- Auto-move icon to BottomLeft when node is resizable to avoid
  overlap with resize handle

RandomNumberModel example:
- Fixed memory leak by reusing timer instead of creating new ones

New examples:
- node_validation: demonstrates NodeValidationState and
  NodeProcessingStatus with status icons
- custom_painter: shows custom AbstractNodePainter and
  AbstractConnectionPainter implementations

New tests:
- TestNodeValidation: validation state and processing status
- TestCustomPainters: custom painter registration
- TestCopyPaste: copy/paste and duplicate operations
- TestZoomFeatures: zoom fit all/selected, scale range
- TestLoopDetection: cycle detection in data flow graphs

Documentation restructure:
- Reorganized into topic-based sections: getting-started/, guide/,
  examples/, api/, migration/
- Added installation guide with Qt SVG dependency note
- Added quickstart tutorial with step-by-step screenshots
- Expanded data-flow guide with validation and processing status
- Added FAQ and v2-to-v3 migration guide

Screenshots and diagrams:
- Added 19 screenshots in docs/_static/screenshots/
- Added PlantUML architecture diagrams in docs/_static/diagrams/
- Moved README showcase images to assets/
- Increased image sizes for better visibility

Build configuration:
- Fixed Sphinx SOURCEDIR path
- Added venv to exclude_patterns

API Reference improvements:
- Better organization by category (Core, Node, Connection, etc.)
- Added missing classes: StyleCollection, CreateCommand, CopyCommand, PasteCommand
- Added new structs: NodeValidationState, ProcessingIconStyle
- Added new enums: NodeProcessingStatus, ProcessingIconPos
- Removed non-existent DuplicateCommand
- Fixed anonymous enum warnings with :no-link: directive

Build fix:
- Added breathe config for local Doxygen XML builds

* fix: resolve test failures in CI environment

TestGraphModel:
- Add loadNode() implementation to support copy/paste operations
- Save and restore node type in saveNode()/loadNode()

TestLoopDetection:
- Add applicationSetup() for DataFlowGraphModel tests
- Use TestDisplayNode (has both in/out ports) instead of
  TestSourceNode (output only) for loop detection tests

TestCustomPainters:
- Simplify to test painter registration without verifying actual
  painting calls (unreliable in headless CI environments)
- Add tests for painter persistence through node lifecycle events

* fix: add DLL export macro to NodeGraphicsObject

Add NODE_EDITOR_PUBLIC macro to NodeGraphicsObject class to properly
export its symbols on Windows. This fixes linker errors when building
examples that use graphModel() and nodeScene() methods.

Error was:
  unresolved external symbol NodeGraphicsObject::graphModel()
  unresolved external symbol NodeGraphicsObject::nodeScene()
